In 1859 Sir Gerard George Aylmer, the 9th Baronet of Donadea began building a circular tower on the top of the Hill of Allen. It was completed in 1863. The names of the workmen are inscribed on the steps.

A large coffin containing human bones was unearthed during the construction. It is said that the bones belonged to Fionn mac Cumhaill himself, so they were duly re-buried under the building site.

The Hill of Allen is a volcanic hill situated in the west of County Kildare, near the village of Allen. According to Irish Mythology, it was the seat of the hunter-warrior Fionn mac Cumhaill and the Fianna. The site is currently part-owned by Roadstone Dublin Limited, so extensive quarrying has noticeably changed the profile of the hill.
